TOBACCO- PIPE.

SPECIFICATION forming part of Letters Patent No. 223,630, dated .Tanuary 20, 1880.

' Application filed May 21, 1879.

To all whom it may concern Be it known that I, STEUBEN T. BACON, of Boston, in the State of Massachusetts, have invented a new and useful Improvement in Tobacco-Pipes, which improvement is fully set forth in the following specification.

The object of my invention is more particularly. to render tobacco=pipe smoking more agreeable and healthy by making the smoke come cooler and softer to the mouth of the smoker than from pipes heretofore made. There is in my invention a more perfect combustion of the tobacco, and it holds fire longer and leaves no condensation in the bowl of the poisonous products through which the smoke passes in an ordinary pipe. These results are attained by the free circulation of air through the perforations in both the bowls of my pipe. When the tobacco is consumed the residuum in the bowl is dry ashes.

My pipe is made with two bowls, with an air-chamber between them, and each bowl is provided with air ports or perforations.

In the drawings, Figure I represents'a perspective view of a pipe made in accordance with this invention, a portion of the outer the construction; and Fig. 2, detached views of the two bowls and seat or joint for connectin g them with the stem.

The inner bowl, A, is provided around its top with a beveled flange, a, which fits into a counter-bevel at the top of the outer bowl, B, so as to assist, in connection with the nipple a, which passes through the bottom of the outer bowl, in holding the said outer bowl firmly in position. Another purpose of the said flange a, which is made to project slightly beyond the circumference of the outer bowl, is for easily lifting said inner bowl from its seat in the joint C, and for the further purpose of preventing particles of tobacco from getting into the air-chamber between the bowls A B when charging the pipe.

The outer bowl is shaped so as to have a tight seat to support it.

The nipple of the inner bowl is perforated through its center,and is inserted in aperforated cork fitted in the seat of the bowls or jointC;

or the cork may be attached to the nipple instead of the seat, or the nipple may be screwed into the seat.

The stem D is inserted or screwed into the seat or joint C.

The different parts are made interchangeable, so that when, from any cause, it is desired to discard the inner bowl, another may be put in its place at a most trifling cost without depreciating the value of the other portions of the pipe.

My pipe may be made of any suitable material, or the different parts may be of different materials. For example, theainner bowl may be of cheap materialwood or clay-while the outer is of a more costly or ornamental material. It may be charged, lighted, and smoked in the same manner as an ordinary pipe, except that it is better not to press the tobacco into the bowl quite as hard as in an ordinary pipe. I

When my pipe is made in pieces, as shown, it affords excellent facilities for cleaning. I may, however, make some with the outer bowl seat or joint and stem in one piece, if desired.

I do not mean to confine myself to anyspecified number of holes or air-ports in either of the bowls, nor to holes of any particular di-' mensions; but I have i'oundhighly satisfactory results to be given when the holes in the inner bowl are about onethirty-second of an inch diameter and fifteen in number, and those in the outer bowl about one-tenth of an inch in diameter and sixteen in number.

Part of the advantages of my invention may be secured by having the outer bowl only perforated.

Having thus described my said invention and the manner in which the same is or may be carried into effect, what I claim, and desire to secure by Letters Patent, is-- A tobacco-pipe having two perforated bowls, with an air-chamber between them, substantially as and for the purposes described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

STEUBEN T. BACON.
